Taking a cue from Octavia Spencer, both Henson and Williams have bought out screenings of Hidden Figures at movie theaters in Virginia, Georgia, Illinois, Texas and Washington D.C. on Sunday. Spencer paid for a free screening of the critically-acclaimed film earlier this month, saying that her own mother would not have been able to afford to take her and her siblings.

Henson, who plays the lead role as NASA physicist and mathematician Katherine Johnson, was inspired to do the same in Houston, Chicago, Atlanta, and of course, her hometown of Washington D.C. On Instagram, she said she was moved by Spencer and “similar actions taken by so many of YOU across the country.” Anonymous donors have been buying out whole screenings.
